This section provides a list of the most common commands and their output for the examples used in this guide.
General commands
show version
Leaf and spine switches must be running a supported version of SmartFabric OS10. Run the show version command to check the operating system version. SmartFabric OS10 is available on Dell Digital Locker (account required).

show interface status
The show interface status | grep up command is used to verify required interfaces are up, and links are established at their appropriate speeds. In this example, ports 1/1/1-1/1/3 are VxRail nodes, port 1/1/9:1 is a jump host, ports 1/1/49-1/1/52 are the VLTi, ports 1/1/53-1/1/54 are uplinks to the external network, and ports 1/1/55-1/1/56 are uplinks to the spines.

show port-channel summary
The show port-channel summary command is used to view port channel numbers, interfaces used, and status. Port channel 1 (number may vary) is the L2 uplink. Port channels 96 through 97 (numbers may vary) are automatically created spine uplinks. The VLTi is automatically configured as a static LAG using port channel 1000. Ports 1/1/53 and 1/1/54 are port channel members, and (P) indicates each is up and active.

The show virtual network command is used to view virtual networks, VLANs, and interfaces assigned to each VLAN. Port channel 1 (number may vary) is the L2 uplink if configured. Port channel 1000 is the VLTi. Interfaces 1/1/1-1/1/3 are connected to VxRail nodes. Interface 1/1/9:1, shown under VLAN 1811, is the jump host port.

show lldp neighbors
The show lldp neighbors command is useful for identifying connected equipment. Interfaces 1/1/1-3 are connected to the VxRail nodes, and Interface 1/1/9:1 is connected to the jump host. Interfaces 1/1/53-54 are connected to the external network, and 1/1/55-56 are connected to the spines. Mgmt1/1/1 is connected to the OOB management switch.

Run the show ip interface brief command to verify connected interfaces are up, and IP addresses are configured correctly.
In the output below, interfaces 1/1/1-1/1/3 are connected to the VxRail nodes, 1/1/49-1/1/52 are the VLTi, and 1/1/53-1/1/54 are L3 uplinks to the external switches. VLAN 4090, Loopback 1, and Loopback 2 are automatically configured by SFS. VLAN 4090 is used for iBGP, Loopback 1 is the router ID, and Loopback 2 is the VTEP IP address.

show ip route
With L3 uplinks, the show ip route command is used to ensure the leaf switches have routes to the external network, 172.19.11.0/24 in this example, to reach the DNS server. This BGP-discovered route is shown in the output below.

VLT commands
show vlt domain_id
This command is used to validate the VLT configuration status. In SmartFabric mode, the VLT domain ID is 255. The Role for one switch in the VLT pair is primary , and its peer switch (not shown) is assigned the Secondary role. The VLTi Link Status and VLT Peer Status must both be up.
